A Victorian man has admitted to slashing an off-duty paramedic with a box cutter during a violent crime spree which ended when he was spotted loitering outside a nearby police station carrying the weapon.

Key points:

Bardic pleaded guilty to nine charges, including intentionally causing injury and theft of a motor vehicle

He was on bail for drug possession charges at the time of the rampage

He will return to court for a plea hearing in May

Adam Bardic, 48, of Capel Sound, attacked the woman as she buckled her two young children into their car seats after picking up fish and chips for dinner in Rosebud, on the Mornington Peninsula, on her way home from work last July.

The then-47-year-old was in uniform when Bardic grabbed her shoulder and pressed his arm across her neck to pin her against her car before slashing her twice across her chest.

The box cutter sliced through her jumper and shirt to inflict a wound about 15 centimetres long, according to court documents.

According to a police summary, Bardic "walked casually away" as the woman yelled for help and compressed her chest wound.

She called triple zero and was taken to hospital where she received 15 stitches.

The woman told police she believed she might have treated her attacker about 18 months earlier, but was not certain.

Bardic, who was seen inhaling from a plastic bag, had earlier tried to get into another car parked behind his victim's, but the driver had locked the doors before he had been able to gain entry, according to court documents.

Bardic threatened takeaway store workers

Bardic fled on his bike and rode to another takeaway store in Rosebud which had just closed.

He banged on the window and yelled "I want food" before smashing the glass with a tomahawk when they refused to serve him, according to court documents.

The owners went outside to follow Bardic but retreated when he raised the tomahawk above his head at them.

Bardic later stole a car from the car park of the Rosebud Hotel and began driving it at high speeds before losing control and veering into the path of an oncoming car.

He crashed the car into a treed area on the Rosebud foreshore, destroying the vehicle.

The crash prompted people from a nearby caravan park to run over and help prise open the car door, which had been jammed shut.

According to court documents, Bardic got out of the car with a hammer and the tomahawk, which he swung at the good Samaritans, causing them to flee.

Several hours later he was arrested when police noticed Bardic loitering outside the Rosebud police station, still carrying the box cutter.

He was on bail for drug possession charges at the time.

Bardic today pleaded guilty in the Melbourne Magistrates' Court to nine charges over the rampage, including intentionally causing injury, theft of a motor vehicle and reckless conduct endangering serious injury.
